Here are some other sources of vitamin C therapy that I found useful.
Now, when I feel like I'm getting sick (or I am sick), I'll megadose with sodium ascorbate (vitamin C) and I feel quite confident that if I or a loved one had swine flu, they could quickly recuperate. If not, increase the dose using a vitamin C IV.
"It’s important to remember that every nutrient you ingest raises or lowers up to nine other nutrients in your body.
Every nutrient needs certain synergistic nutrients, and if you are already low in those synergistic nutrients, taking more of one thing will only further deplete the existing deficient levels, worsening any problems relating to that nutrient’s metabolism.
For example, taking large doses of vitamin C (ascorbic acid) on a regular basis lowers your level of copper, so if you are already deficient in copper and take high doses of vitamin C, you can compromise your immune system.
So, whereas temporarily taking megadoses of vitamin C supplements to combat a case of the cold or flu is likely not going to cause a problem, for long-term, daily use, your best bet is to eat an diet that is full of high quality organic vegetables and fruits that are minimally processed. Not only will you get vitamin C, but you will get all the other accessory nutrients and micronutrients that are needed to optimize it."
